Frequently Asked Questions

Why are my potatoes au gratin not creamy enough?

A not-so-creamy potatoes au gratin is a bit like a soggy bottom on a Great British Baking Show cake nobody wants it! Usually, this happens because the sauce wasn't thick enough before baking, or the potatoes absorbed too much liquid.

Be sure to simmer your cream sauce until it slightly thickens and ensure potatoes are thinly sliced and not overcrowded in the dish. A touch more Gruyère on top never hurts either!

Can I make potatoes au gratin ahead of time?

Absolutely! You can assemble the potatoes au gratin up to a day in advance. Just cover it tightly and store it in the fridge. When ready to bake, add about 15-20 minutes to the cooking time to ensure it’s heated through.

Think of it as prepping the night before a lavish garden party - leaving you more time to enjoy a Pimms!

What's the best way to store leftover potatoes au gratin?

Store leftover potatoes au gratin in an airtight container in the fridge for up to 3-4 days. To reheat, you can microwave individual portions (though the texture won't be quite as good) or reheat the entire dish in a 350°F (175°C) oven until warmed through.

It's still yummy the next day, even if it loses a bit of its original charm!

Can I freeze potatoes au gratin?

Freezing potatoes au gratin is not recommended as the cream sauce can separate and become grainy upon thawing, and the potatoes themselves can become mushy. The texture changes can really impact enjoyment of the dish, but if you must, freeze in an airtight container after it's completely cooled, and plan to use it in a casserole or other dish where the texture isn't as crucial.

What are some variations I can try for my potatoes au gratin?

Potatoes au gratin is a blank canvas for flavor! Try adding cooked bacon or ham for a meaty twist. You could also incorporate different cheeses like cheddar, fontina, or even a little bit of blue cheese for a bolder flavor.

Some people like to add thinly sliced leeks or caramelized onions to the potato layers for extra depth. It's your chance to be a kitchen rockstar and put your own spin on a classic!

I don't have Gruyère cheese. What's a good substitute for my potatoes au gratin?

No Gruyère? No worries! Emmental or Jarlsberg are excellent substitutes, offering similar nutty and slightly sweet flavors with great melting properties. Provolone is another option, though it has a milder flavor.

Avoid very sharp or strong cheeses, as they can overpower the delicate flavors of the potatoes and cream. Think of it like choosing the right hat for a posh event - you want it to complement, not clash!
